In North Africa… A major British offensive, Operation Battleaxe, begins. The aim is to relieve Tobruk. Wavell is still reluctant to attack, largely because the tanks which recently arrived on the Operation Tiger convoy have had many mechanical faults and the time taken for repairs means that the troops have had a very short training period. Although the two divisions involved, 4th Indian and 7th Armored, are both experience formations, they are not at full strength and have been further weakened by changes in command. General Noel Beresford-Pierse is in charge of the attack. Three columns are sent forward, one to Halfaya Pass, one to Fort Capuzzo along the edge of the escarpment and one inland to Hafid Ridge. The attack of Matilda tanks is beaten off at Halfaya by the emplaced 88mm guns, and without tank support the infantry there can achieve nothing. A force of lighter cruiser tanks similarly loses heavily at Hafid Ridge. Some success is achieved at Capuzzo, however. The German radio intelligence gives them excellent tactical information and their dispositions of 5th Light forward and 15th Panzer watching Tobruk are more than adequate. On the whole Rommel is content to defend on the first day and, indeed, by the end of the day the British tank losses already leave them at a disadvantage.
In Syria… A counterattack by the Vichy French forces succeeds in retaking part of the town of Marjayoun and some nearby positions. However, both to the west on the coast, where Sidon is taken by Austrialian forces and to the east in the approaches to Damascus, where Kiswe falls, the Allied advance is still going well.
